Abstract
The utility model relates to a wet mixer for petroleum coke powder and catalyst used for preparing lithium battery negative electrode materials, composed of a frame and a mixing tank, which is characterized in that: the frame is L-shaped, and the lower part thereof is a base plate (1); the vertical pole (2) of the base plate is a force-bearing support, in which a motor and a transmission are disposed; the vertical pole is connected with the mixing tank (4) via a rotary shaft (3); the mixing tank (4) is a stainless steel prismatic empty tank, and the middle thereof is fixedly connected with the rotary shaft (3); a material charge-discharge hole (5) is disposed at a prismatic pointed end; and a sealing cover (6) is disposed on the charge-discharge hole (5). The wet mixer for petroleum coke powder and catalyst used for preparing lithium battery negative electrode materials disclosed by the utility model is simple and reasonable in structure, easy to manufacture, and convenient to charge and discharge materials while using; the wet mixing is thorough and uniform, so that the demand of adding a graphite catalyst in the crushed petroleum coke material powder to wet-mix via an organic solvent is completely achieved.
Description
Technical field
The utility model belongs to the materials processing technology field, tool this locality a kind of petroleum coke powder, catalyst wet mixing machine for preparing lithium cell cathode material of saying so.
Background technology
In recent years, lithium rechargeable battery is owing to have characteristics such as volume is little, in light weight, thereby in hand portable equipments such as mobile phone, compact video, notebook computer, obtained using widely.Generally speaking, lithium rechargeable battery selects for use carbon element as its negative material.Its preparation method is: (1) petroleum coke raw material such as pulverizes at preliminary treatment; (2) add graphitization catalyst in the petroleum coke raw meal after will pulverizing through the organic solvent wet mixing; (3) petroleum coke raw material above-mentioned adding catalyst, after pulverizing is being carried out graphitization processing in nitrogen, argon gas or vacuum environment, under the temperature of 2400-3000 ℃; (4) material of gained after the above-mentioned graphitization processing such as is sieved at post processing.Add graphitization catalyst in the petroleum coke raw meal after its operation (2) will be pulverized through the organic solvent wet mixing, need a kind of mixing machine that can reach the wet mixing requirement.
The utility model content
The purpose of the utility model is exactly can reach adding the mixing machine that graphitization catalyst requires through the organic solvent wet mixing in the petroleum coke raw meal after pulverizing in order to provide a kind of.
To achieve these goals, the utility model has adopted following technical scheme: petroleum coke powder, the catalyst wet mixing machine of preparation lithium cell cathode material, form by frame and blend tank; Frame is " L " type, and the bottom is a bedplate 1, and its column 2 is a bearing bracket; Be provided with motor, speed changer in it, connect blend tank 4 through turning cylinder 3, blend tank 4 is a stainless steel prismatic slack tank; Be connected with turning cylinder 3 wherein, the prismatic tip is provided with a material handling mouth 5, and loading hatch 5 is provided with capping 6.
Owing to adopted above-mentioned technical solution; The utility model has well been realized its goal of the invention; Simple and reasonable, easy to manufacture, material handling is convenient during use; Wet mixing is thorough, even, has reached fully to add the requirement of graphitization catalyst through the organic solvent wet mixing in the petroleum coke raw meal after will pulverizing.
Description of drawings
Accompanying drawing is the concrete structure sketch map of the utility model;
The specific embodiment
Shown in accompanying drawing, petroleum coke powder, the catalyst wet mixing machine of preparation lithium cell cathode material are made up of frame and blend tank; Frame is " L " type, and the bottom is a bedplate 1, and its column 2 is a bearing bracket; Be provided with motor, speed changer in it, connect blend tank 4 through turning cylinder 3, blend tank 4 is a stainless steel prismatic slack tank; Be connected with turning cylinder 3 wherein, the prismatic tip is provided with a material handling mouth 5, and loading hatch 5 is provided with capping 6.
The operation principle and the process of the utility model are following: at first rotate blend tank 4 with hand and make loading hatch 5 up, screw off capping 6, petroleum coke powder and graphitization catalyst, the organic solvent of need wet mixing dropped in the blend tank 4 in proportion; Cover tight capping 6 then, start motor, turning cylinder 3 drives blend tank 4 and rotates; Thereby the material that makes 4 li of blend tanks does not stop to stir, reach requirement after, turn off motor; Make blend tank 4 forward loading hatch 5 to and stop downwards, screw off capping 6, the slurry after the tipping wet mixing gets final product.
